TRANSMISSION LUBRICATION SYSTEM
The large section of the pump pulls oil from
transmission reservoir (9) and differential reservoir
(11) through the magnetic screen filters (12) and
(13). The flow of oil from the large section of the
pump goes to main reservoir (10). An opening in
the wall between main reservoir (10) and differen-
tial reservoir (11) lets extra oil go from main reser-
voir (10) to differential reservoir (11).
DIRECTION CLUTCH LUBRICATION
The direction clutches get lubrication oil from
the main relief valve. The flow of oil goes through
the center of the forward and reverse clutch shafts.
The lubrication of both clutches is the same. For
the purpose of illustration, the lubrication for the
FORWARD clutch is shown.
There are three passages connected to the center
passage of the direction clutch shaft. Passage (4) is
used to send oil to the clutch plates for cooling and
lubrication. Passage (3) is used for lubrication of
the taper bearings of the output gear. Passage (2) is
used only when the direction clutch is engaged.
When the FORWARD direction clutch is engaged,
the flow of oil through passages (2) and (4) gives
extra lubrication to the direction clutch. When the
direction clutch is not engaged, passage (2) is not
in alignment with hole (1) in the piston and
passage (4) is the only passage that gives lubrica-
tion to the direction clutch.
LUBRICATION FOR TRANSMISSION GEARS
The splines on the input shaft and the flywheel
adapter get lubrication from a passage in the center
of the pump drive shaft. The passage in the drive
shaft is connected to an opening in the large
section of the pump.
